- •
A crack monitoring scheme based on rosette eddy current array sensor is put forward.
- •
Equivalent finite element model is in good agreement with the validation experimental results.
- •
The sensor integrated with different electromagnetic property washer model sensitivity is optimized.
- •
The washer with high relative permeability and low conductivity can effectively boost the system monitoring crack damage sensitivity.
